Many people tend to overlook a critical issue when choosing DEX automation trading tools—the way private keys are stored.

Many products seem powerful, but the underlying logic is actually very risky: they upload your private key to their own servers, some store it in plaintext, others store it "encrypted" (but encryption does not equal security). This may not sound so alarming at first, but what are the potential consequences?

Once your private key is stored on someone else's server, in theory, their internal staff can access it. Hackers want to get it? That’s just a matter of breaching that barrier. Once broken, the risk level skyrockets—your assets are exposed just like they would be on a centralized exchange. The only difference is, this isn’t a well-known major platform, but a small team’s server.

Therefore, before using any tool that requires authorization with your private key, the first thing to ask is: how do they store it? If the answer is "uploaded to our server," then you should think carefully. Your wallet security ultimately depends on your own vigilance.
